Built-in Documentation broken, how do I get it working again?

A few months ago the built in documentation would never open no matter what I typed in and however many times I tried. I thought that updating MATLAB would fix the problem. It did not. I upgraded from 2018a to 2018b today and the built in documentation still does not display anything. A ghost window opens up in the background, but is not highlighted initially. I need to go to my taskbar and click on the separate window to show it. It is the smallest window you can imagine in the upper left corner with no content whatsoever. When I click on it, it closes automatically. Please advise.

Since it's an installation issue you can get free and fast telephone help. Of course since you waited until the weekend, now you'll have to wait until Monday.
